Description

Eliminate compromise in your race tire.

The Grand Prix 4000 S II is even grippier, more durable, and faster than its predecessor. That's because Continental is able to improve their exclusive Black Chili compound just a little bit every year, thanks to their continued dedication to research and development.

What is Black Chili? It's a unique rubber formula with an ultra-dense construction and high silica content, allowing it to deliver outstanding grip and blazing fast speeds. This cutting-edge formula is also optimized for reliability and longevity, making it a great choice when both performance and durability are top priorities.

The GP 4000 S II also features Conti's patented Vectran puncture protection breaker. Vectran was originally developed by NASA in the construction of space shuttles and suits, and Continental has brought its otherworldly lightweight protection to bike tires, making these lightweight tires impressively flat-resistant.

All in all, the GP 4000 S II is Continental's most advanced racing clincher yet, with a truly unique blend of speed, durability, and, now, aesthetics. Thanks to the high-tech materials and years of testing and development, the GP 4000 S II delivers low rolling resistance and superb handling with exceptional puncture protection and higher mileage performance than a typical race tire.

These are by far the best road tires I've ever ridden. The roads in my area are riddled with debris as a result of all the rain we've had here on the east coast so having tires with extra puncture protection is a must. I realize no tire is completely impervious, but these up your chances of not having a flat.

This tire has just the right amount of road-gripping firmness while delivering a very comfortable ride. I'm very happy with the feel and handling. Its a big improvement over what was on my road bike previously.

I had previously ridden on Vittoria Open Corsa clinchers. These ride as fast as the Vit's but not as supple. The Vit's are good for a 1500 miles max. and seem to cut very easily.The speed advantage the Conti's provide more than makes up for the less supple ride quality and so far I've experienced no punctures. When on sale I usually buy a pair.

These are tough, flats occur like anything else but tend to be very few and far between. They are very hard to mount at first because of stiffness but it gets easier after some use. They are also comfortable on a long distance ride. My only other qualm is after about 2,500 miles or so, they tend to shed some threads fairly regularly though its probably about time to replace them by then.

Super fast, super grippy, relatively long lasting. These have been my go-to tire for as long as I can remember. New bikes get them installed near immediately. I use these daily and no complaints on longevity, but the 4-Season isn't a bad option if you're not racing.

Excellent road tires as they grip on wet pavement and are resistant to the occasionally broken beer bottles people leave behind. They are also resistant to the kiawe (Hawaiian Mesquite) thorns strewn all over the islands.

I've been riding on these tires for the past 15k miles or so. I've had maybe 2-3 flats in all those miles. I ride mostly on county tar & chip seal roads. I've always used size 700x25 but went up to 700x28 the last set. I decreased my tire pressure from about 100 to 90psi. They seem to be more comfortable with little speed difference. Get these tires when on sale, you'll be happy.

Like many cyclists, I've tried a lot of different high performance tires looking for that one tire that excels at everything. In the end, I use GP4000's on all of my wheels. A few tires have a more supple ride, a few corner better. Other tires are miserable to fit or have weak side walls or get lousy mileage or are prone to flats. GP4000,s just inspire confidence. They corner well in wet and dry, I get excellent mileage, (3,000 mi. plus), average about 1 flat per year, never had a side wall problem and they have relatively low rolling resistance. I've hammered these tires on So. California roads and the GP4000.s always get me home safely.

The Continental GP 4000 S II is a smooth, fast tire. I use it on a Trek Domane for added cush on chip seal roads. The larger (28c) size provides a solid but smooth ride. I can't tell any difference in rolling resistance from the previous 25c tires used. I highly recommend this tire.
